Research On Optimization Of Schemes To Dapengwan's Traffic Separation Scheme

Dapeng Bay has open waters and good natural water depth conditions.Ships entering and leaving Shenzhen and Hong Kong sail in the waters.The flow of ships entering and leaving Dapeng Bay waters is relatively large,with an average daily flow of more than 140 ships.The composition of ship traffic flow is very complicated,among which there are many large ships such as containers,oil tankers and LNG ships with a ship length of more than 200m.The development trend is obvious.It is estimated that the daily average flow of ships in Dapeng Bay waters will reach about 179 ships in 2030.All kinds of ships are mainly concentrated in the waters of the main route of Dapeng Bay.There are many cross-over conditions,which greatly affect the navigation safety of the waters.As a result,there is a high risk of navigation in Dapeng Bay.Therefore,it is necessary to establish Dapeng Bay TSS(Traffic Separation Scheme)and simplify the form of vessel traffic flow in the main route.Basing on a combination of theoretical research,field research and expert consultation,and concerning regulations such as General Provisions on Ships' Routeing,this article establishes index system of Dapeng Bay TSS by factors of navigation environment,management and human.At last,this article evaluates the amendment scheme of Dapeng Bay TSS by evaluation model based on improved entropy method after taking full consideration of the inner relationship between index factors,and verifies the feasibility of evaluation method by Set-Pair Analysis theory,and further analysis the results.The optimized amendment scheme of Dapeng Bay TSS is approved by navigation officers,shipping company and maritime traffic control department.This article provides relevant department a reference for establishing of Dapeng Bay TSS.
